In this tutorial we interface 16×2 LCD display with ESP8266 NodeMCU without using I2C and with minimum pins i.e. using only 3 pins. To interface LCD with ESP8266 we need at least 6 IO lines but ESP already have very few IO lines, to expand IO lines we use serial to parallel shift register IC 74HC595.

Nodemcu pinout
Nodemcu pinout is having labels D0 to D8 and RX-TX but when programming it using Arduino IDE we observe that its labels are not matching with IO connections. Lets see actual connections of NodeMCU with ESP8266 i.e. ESP-12.
NodeMCU is an open source IoT platform. It includes firmware which runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which is based on the ESP-12 module. The term “NodeMCU” by default refers to the firmware rather than the dev kits. Continue reading Nodemcu pinout
